Recycling Thermoplastics

Recycling thermoplastics is key for a sustainable future. Recycling thermoplastics helps the environment and saves money by cutting down waste and using resources wisely¹³.

Importance of Recycling

Thermoplastics are vital for green manufacturing. About 75% of plastic made worldwide is thermoplastic¹³. They can be recycled many times, making them very useful¹⁴.

Recycling Process Overview

The recycling process for thermoplastics includes several steps:

• Collecting used materials
• Sorting by plastic type
• Cleaning and preparing
• Turning them into new products

There are four main ways to recycle thermoplastics:

1. Primary recycling (closed-loop)
2. Secondary recycling (downgrading)
3. Tertiary recycling (chemical or feedstock)
4. Quaternary recycling (energy recovery)

Challenges in Recycling

Recycling thermoplastics has big challenges. Chemical additives can lower material quality with each recycle¹⁴. Also, old contaminants can make recycling harder¹³.

To overcome these issues, we need new ideas and better recycling tech. For example, the car industry is using one type of plastic to make recycling easier¹³.

Only a tiny part of plastic waste is recycled today. About 9% of plastic is recycled¹⁵. We need better recycling systems and tech fast.
